The present invention relates to a loading control apparatus capable of aligning the mail automatically. A corresponding output signal supplied by the power amplifier circuit is measured, wherein at each moment the output signal has a measured amplitude and a measured phase. The distance to place an ablation electrode surface from a target tissue surface may be selected based on various operating parameter values andor operating condition values. The host device determines whether to allow firmware exchange in accordance with the received response information, and if firmware exchange is enabled, generates information about multiple paths with the storage device. The distortion level measurement unit measures fingerprint distance differences, and arousal and valence distance differences.
